Cannon scene concept

Hey there!

I’m working on this cannon scene and I’d like to get some critique on the concept. The cannon and the grass are 3d models, but the rest is just images and paintover in Krita. The look I’m going for is something between these two:

Harsh critique is also welcome, I’m currently still in the progress of figuring out what to do.

Thanks in advance!

try black on the iron. or a real dark brown with reduced color intensity (means less color, more dark-grey). the cannon looks good

Thanks for the reply!
